JavaScript时间倒计时的代码

1、js时间倒计时

<script language="javascript">
/**
 * 倒计时
 * www.jb200.com
*/
function JSTime(dateTime) { 
    var  aDate,  oDate1,  oDate2,  iDays;  
 var  Digital=new  Date();
 var  month  =  Digital.getMonth()+1;
 var  year  =  Digital.getYear();
 var day= Digital.getDate();
 var hour=Digital.getHours();
 var minute=Digital.getMinutes();
 var sec.getSeconds();
 oDate1  =  new  Date(month  +  '-'  +  day  +  '-'  +  year+' '+hour+':'+minute+':'+second); //转换为12-18-2006格式  
     //  oDate2  =  new  Date(12  +  '-'  + 03+  '-'  + 2008+' '+15+':'+00+':'+00); 
oDate2  =  new  Date(dateTime);   
if(oDate1<=oDate2){    
 var remainDay,remainHour,remainMinute,remainSecond; 
 iDays  =  parseInt(Math.abs(oDate1  -  oDate2));//把相差的毫秒数转换为天数  
 remainDay=iDays /  1000  /  60  /  60  /24;
 remainDay = Math.floor(iDays/1000/3600/24); 
iDays = iDays - (remainDay*1000*3600*24); 
   remainHour = Math.floor(iDays/1000/3600); 
   iDays = iDays - (remainHour*1000*3600); 
   remainMinute = Math.floor(iDays/1000/60); 
   iDays = iDays - (remainMinute*1000*60); 
   remainSecond = Math.floor(iDays/1000); 
  iDays = remainDay+"天"+remainHour+"小时"+remainMinute+"分"+remainSecond+"秒"; 
  document.getElementById('time1').innerHTML=iDays;
}else{
 document.getElementById('time1').innerHTML='活动时间已开始，您有一天的体验时间，赶快体验吧！';
}
 }
 window.setInterval("JSTime('12-03-2008 10:00:00')",1000);
</script>

附：距离某个时间还有多少天

<script language="javascript">
/**
 * 距离某个时间的天数
 * www.jb200.com
*/
function  datediff(today){    //sDate1和sDate2是yyyy-mm-dd格式  
 var  aDate,  oDate1,  oDate2,  iDays;  
 var  Digital=new  Date();
 var  month  =  Digital.getMonth()+1;
 var  year  =  Digital.getYear();
 var day= Digital.getDate();
  oDate1  =  new  Date(month  +  '-'  +  day  +  '-'  +  year); //转换为12-18-2006格式  
 oDate2  =  new  Date(month  +  '-'  + today  +  '-'  +  year);  
if(oDate1<oDate2){
  iDays  =  parseInt(Math.abs(oDate1  -  oDate2)  /  1000  /  60  /  60  /24);    //把相差的毫秒数转换为天数  
 document.getElementById('dateti').innerHTML=iDays;
}else{
   oDate2  =  new  Date((month+1)  +  '-'  + today  +  '-'  +  year); 
   iDays  =  parseInt(Math.abs(oDate1  -  oDate2)  /  1000  /  60  /  60  /24);
   document.getElementById('dateti').innerHTML=iDays;
}
 return  iDays;  
}
</script>
